With various percent constituent ratio based on four molecules including TKTL1, J‐CHAIN, PCM1 and TRGC2 (Figure S6f), the critical cell clusters were reset through key Coronavirus‐COVID‐19 and NSCLC‐related path‐feedbacks, especially in clusters‐2/‐3, and illustrated by pathway heatmap based on QuSAGE (Figure S6g) and GOPath/Log10P analysis (Figure S6h). The gene discussed is TRGC2; the disease is COVID-19.
